Fill hole, 3 interference of rolling bearing be mounted on support plate 7 mounting hole in, 2 elastic conjunction of rotary sleeve in the inner ring of rolling bearing 3,
Facilitate the rotation of rotary sleeve 2.Support plate 7 and 8 seam allowance location fit of water lubriucated bearing gantry motor holder, and will be propped up by bolt
Fagging 7 is fixedly connected on the electric machine support 8 of water lubriucated bearing rack, and extraction cover board 10 is matched with 16 seam allowance of water lubrication journal bearing
Two screws 12 of merga pass are fixedly connected cover board 10 is extracted with water lubrication journal bearing 16.1 lower end of lift lever is provided with outer
The center of screw thread, extraction cover board 10 is provided with the threaded hole to match with the external screw thread of lift lever 1,1 lower end spiral shell of lift lever
Line is connected in the threaded hole of extraction cover board 10, and is fastened lift lever 1 with extraction cover board 10 by nut 9 and connected, to avoid
Extraction bar 1 is with extraction cover board 10 because weight causes to thread off；The upper end of lift lever 1 is also equipped with external screw thread, and the inner wall of rotary sleeve 2 is set
It is equipped with the internal thread to match with the external screw thread of lift lever 1, the upper end of lift lever 1 is screwed onto in rotary sleeve 2, rotates rotary sleeve 2
The lift lever being spirally connected with rotary sleeve 21 can be driven to move up and down, the movement of lift lever 1 can drive the extraction lid being attached thereto
Plate 10 moves, and is moved to drive and extract the water lubrication journal bearing 16 that cover board 10 is fixedly connected, to which water lubrication is radial
Bearing 16 removes and installs.
It is also equal around lift lever 1 in order to enhance the stability for driving journal bearing 16 to move when lift lever 1 moves up and down
It is even to be provided with four guide rods 4 and four guide sleeves 5, in the threaded hole that guide sleeve 5 is screwed onto in support plate 7 and pass through spiral shell
Mother 6 fixes, and the lower end of guide rod 4 is fixedly connected with extraction cover board 10, and the upper end of guide rod 4 is slidably disposed in
In guide sleeve 5, and there are very small gaps between guide rod 4 and guide sleeve 5, it is ensured that guide rod 4 is being oriented to
It moves up and down and does not shake in casing 5, meanwhile, guide rod 4 and extraction 10 screw thread of cover board rigid connection can ensure to lead
To the accuracy of 4 elevating movement of bar.
Water lubrication journal bearing 16 is assemblied in by feather key 13 in bear box 11, water lubrication journal bearing 16 and guiding
Key 13 is fixedly connected by screw, and feather key 13 is then screwed onto on 11 inner wall of bear box, and 11 side of bear box is provided with
Electric vortex displacement sensor probe 15, electric vortex displacement sensor probe 15 is by the external thread bolt connection on its surface in bear box
On a threaded hole on 11 side walls, play the role of measuring the displacement that the journal bearing 16 in bear box 11 moves.Bearing
14 seam allowance of intermediate support of shell 11 and water lubriucated bearing rack position and rely on bolt closing fixation, the intermediate support 14 and
8 seam allowance of the electric machine support positions and conjunction is fixed by bolt.
The operation principle of a kind of bush(ing) bearing installation and provision for disengagement provided in an embodiment of the present invention is as follows：
Referring to Fig. 2, cover board 10 will be promoted and consolidated with two screws 12 with being matched to merge by dismounting object, that is, 16 seam allowance of journal bearing
Tightly, by support plate 7 and 8 seam allowance location fit of water lubriucated bearing gantry motor holder, and pass through bolt tightening.Dismantle journal bearing
When 16, rotary sleeve 2 is rotated clockwise, rotary motion of the rotary sleeve 2 in rolling bearing 3 is changed into rotary sleeve 2 and lift lever 1
Axial movement, lift lever 1 moves upwards, and extraction cover board 10 is driven to move up, and then extracts cover board 10 and drive by dismounting object (diameter
To bearing 16) it moves up, until journal bearing 16 is split out out of bear box 11.Due to being deposited between guide rod 4 and guide sleeve 5
In very small gap, it can ensure that guide rod 4 moves in guide sleeve 5 but does not shake, and guide rod 4 and extraction
10 screw thread of cover board is rigidly connected, it is ensured that the accuracy of extraction 10 elevating movement of cover board.When needing to install journal bearing 16,
Rotation rotary sleeve 2, lift lever 1 move downward counterclockwise, and extraction cover board 10 is driven to move down, and then extract the drive of cover board 10 and dismounted
Object (journal bearing 16) moves down, until journal bearing 16 is installed in place.
Positioned since 8 seam allowance of electric machine support of support plate 7 and water lubriucated bearing rack coordinates, meanwhile, extraction cover board 10 with
Water lubrication journal bearing 16 is also seam allowance cooperation positioning, therefore the precision for capableing of realization device and water lubrication journal bearing 16 is fixed
Position, be finally completed the installation centering and dismounting of water lubrication journal bearing 16, and ensure water lubrication journal bearing 16 dismounting with
It can be concentric with bear box 11 when installation.Also, since electric vortex displacement sensor probe 15 is existed by its external thread bolt connection
On the threaded hole of 11 side wall of bear box, the water lubrication journal bearing 16 in bear box 11 is not touched, therefore can be not
Water lubrication journal bearing 16 can be realized in electric vortex displacement sensor probe 15 installation and dismounting must be removed.
It should be noted last that the above specific implementation mode is merely illustrative of the technical solution of the present invention and unrestricted,
Although being described the invention in detail with reference to example, it will be understood by those of ordinary skill in the art that, it can be to the present invention
Technical solution be modified or replaced equivalently, without departing from the spirit of the technical scheme of the invention and range, should all cover
In the scope of the claims of the present invention.
